Gatherer doesn't get to the optimal dropout

[Koufalex]

The gatherer decides to go to the closest farmstead / town center but it seems the way the distance is determined is by straight line which is not always optimal.

In the case that I have documented on the pictures, the gatherer (the rider) goes to the farmstead although being farther away than the town center considering the path he has to follow to get to the farmstead passes directly by the town center.

Picture 1: The gathering point is closer to the farmstead than the town center

Picture 2: But to get to the farmstead he passes by the town center

Picture 3: Finally he goes to the farmstead but after covering more distance than it is necessary. 

Any feedback is welcome
